In this groundbreaking book, Dr. Michael F. Roizen and Dr. Mehmet C. Oz bust the myths and stereotypes about the way we view ourselves -- and how we define beauty. Most people think that beauty revolves around such things as lipstick, sweet eyes, or skinny jeans -- all those things that we can see (and obsess over) in the mirror. But the fact is that beauty isn't some superficial pursuit, and it's not some random act that you can thank (or curse) your ancestors for. There are, in fact, scientific standards to beauty. Beauty is purposeful because it's how humans have historically communicated who we are to potential mates. Beauty, in fact, is really about your health and happiness. In these pages, you'll find out why beauty isn't as much about your vanity as it is about your humanity. Dr. Roizen and Dr. Oz take a scientific, informative, and entertaining look at the three levels of beauty and explain how they all work together to form a complete and authentic YOU. With their usual candor and honesty, the doctors break down the mechanics of beauty and explain how little adjustments in your routine can help you become a happier, healthier person.
